- UsersSite - DC2 - Layer 3 (the same VLAN 10) (ACCESS Link)
There will be a network core switch on every site (3750 or 4500 - haven't decided yet). So the 3 network cores will be interconnected as explained above. (see image attached).
There will be an HSRP configured between the 2 network cores (DC1 and DC2).
So in order to access a ressource on DC1 - the users site has to send its packets to the gateway (which is the HSRP address on vlan 10 of DC1 and DC2).
THE PROBLEM is that at Layer 2 - there is STP enabled, and there is a loop, between these 3 sites. So, in case if, for example, DC1 is the active core, and STP decided to block the port that connects Users site with DC1 site - IT WON'T WORK.
Could you please tell me how can this design be modified, or what configuration has to be deployed for this to work ?
Can you please provide bit more clarity on the number of VLANS. From the figure, I could understand that user site Switch have only local VLAN which is connected to Core switch by an L3 link. You would like to configure HSRP under L3 interface / under SVI.
